Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare the safety profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false, openWorldHint=false). The description usefully adds the authorization requirement (owner or lead) and that the project is private/visible only to authorized workers, but says nothing about non-idempotency, duplicate-name behavior, or side effects such as invites being created.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the action, then the permission gate, then the sequencing advice. No filler and every sentence carries distinct information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 4-parameter creation tool with no output schema, the definition covers purpose, permission, and ordering, but never indicates what comes back (e.g. a project reference needed by corrobyte_start_project_task or corrobyte_claim_project_task) or whether repeated calls with the same name create duplicates. Those gaps are minor against annotations that already cover the safety profile, but they leave the agent guessing at the handoff.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all four parameters are already documented, and the baseline is 3. The description adds modest meaning by framing objective and constraints as the shared boundary every contributor receives, but contributes no format, length, or value constraints beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Create a private project') and scopes it to a workspace, which cleanly separates it from corrobyte_create_workspace and the project-lifecycle siblings (start/claim/get state). No schema opening is needed to know what it produces.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a real precondition ('Requires workspace owner or lead access') and a sequencing rule ('Define the objective and constraints before starting workers'), which tells the agent when in the workflow to call it. It stops short of naming an alternative tool or exclusion case (e.g. how it differs from creating a workspace invite), so it is clear context rather than full routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
